Sacrococcygeal giant hemangiopericytoma: a rare presentation and management

Hemangiopericytoma is a tumor derivated from the mesenchymal cells that surround the capillary of blood vessels. It has a several anatomic localization and clinic scenarios, it´s presentation with a media in the 6th decade; an early diagnostic and treatment represents a better clinic scenario for the patient. The next article presents a case report of a 51 years old man with a tumor localized in the sacrococcygeal space, with big dimensions that limited his daily activities without other symptomatology, image studies with no evidence of distant progression. Surgical resection was performed, removing mass depending from mayor and minor gluteus, achieving an immediate reconstruction with a satisfactory aesthetic and functional result. The authors presented this rare case due to the lack of published information and how it can be treated to achieve good results.

Versatility of the estlander flap: upper lip, lower lip and comissure reconstruction due to a dog bite

Background: Dog bites continue to be a frequent cause for plastic and reconstructive services in the world. The grand majority of these cases affect the head and neck area; and more often than not they involve the commissure and the lips. The latter leading to an increased level of difficulty and a substantial decrease on the posibilities for a successful reconstruction. This case report focuses on the exploration of the Abbe-Estlander flap as an efficient alternative in most of these cases.Methods: We present two clinical cases involving dog bites where the affected area of both patients was estimated to be one third of the total volume of the lip. Both patients required emergency reconstructive surgery. An Estlander flap was successfully performed in both instances. The purpose of the article is to share the results and motivate the medical community to continue to use this method as a strong avenue for an effective recovery.Results: After two months of the surgery, the team followed up with both patients and they were satisfied with the results. Patient A presented adequate healing of the wound; a lack of alignment of the mucocutaneous rim and rounding of the commissure was observed. Phonation, oral continence without any leakage and complete closure of the lip were also part of the recovery assessment. Patient B presented adequate healing of the wound, phonation and medium oral continence with occasional leakage of liquids and incomplete closure.Conclusions: The Abbe-Estlander flap is still an excellent reconstructive alternative for upper and lower lip reconstruction where the affected area is up to one third of the total volume. As long as the commissure involvement represents minimum difficulty, both aesthetic and functional objectives can be successfully attained using this flap.

Pediatric nasal reconstruction with frontal flap: a case report

Authors presented the case of a 4-year-old male patient who suffered a dog bite on his face with partial amputation of the nasal tip, managed at another institution conservatively, so that one year after the injury he came for the nasal deformity. A frontal flap was performed for reconstruction achieving excellent results, coverage was achieved with similar characteristics of the skin as color and texture. The patient had a follow-up of 5 years with an appropriate course. Authors presented the case due to few reports in the literature of its use in children, where it can be observed that it is an excellent reconstructive tool.
